This commit improves memory management by respecting Linux cgroup v1/v2 limits and introduces a configurable memory budget for the new `rebuild` subcommand to prevent OOM during index reconstruction. The rebuild process now supports filtering, compaction, and parallelization. Diagnostic capabilities are expanded with debug-level tracing for partition merges, k-mer expansion tracking, and utility flags for label renaming, matrix size breakdowns, per-genome counts, and partition distribution reporting. Accessor methods for active and remaining memory have also been added to the stats struct.
